Thermostatic valve for a cooling circuit

摘要

The valve has a mobile flap (44) to control fluid passage between inlet and outlet orifices of a case (32). The flap slides such that it is separated from its fixed reception seat (46), when the pressure on the side where the flap is connected to a thermostatic unit becomes very high with respect to the other side of the flap. An elastic unit returns the flap when the pressure difference is within a tolerated range.
